Application filed August 2?, 1520. Serial Nm 406,563.

To all whom if; may concern:

Be it known that l, MAJOR Pi-riLnnn'r, a citizen of the United States, residiiu;- at Windsor7 in the county of Sonoma and State of California.7 have invented new and useful Improvements in Pruning` llevices7 of which the following is a speciiication.

rlhis invention relates to improvements in pruning shears and has for an object the provision of a device of this character in which a maximum of leverage is exerted upon the shear blades.

Another object is the provision of a prun` ing' shear in which the movable blade or knife is guided between spaced blades and lateral movement or spreadingv of the blades prevented, thereby adding greatly to the effectiveness of the device.

Another object is the provision of a device of this character which is simple and durable of construction and in which the movable blade or knife may be easily and quickly removed for sharpening.

With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying` drawings and pointed out in the appended claim.

1n the drawings `litigare 1 is a side elevation of the invention, the shear blades beingr shown in closed position.

Figure 2 is a similar view showing the blades open.

Figure 3 is an edge view.

Figure i is an enlarged transverse section en a line with the pivotal connection of the handles.

i Figure 5 is a similar view through the pivotal connection of the shear blades.

Figure 6 is a detailed view of the pivoted blade.

Figure 7 is a detailed perspective view of the soclzeted handle member which carries the rigid shear blade.

Referring` to the drawings in detail,

wherein like characters of reference denote corresponding parts, the reference characters 10 and 11 designate respective1 soci;-

eted handle members which are connected to the rigid shear blade 12 and the movable shear blade 13.

These socketed handle members are preferably formed of sheet metal, one end being bent into substantially cylindrical form as shown at lei for the reception of a wooden handle, a portion of which is indicated at 15. rlhe remainder of the handle members are flattened, being' bent longitudinally and spaced apart as shown atl@ so as to provide a longitudinal groove.

Secure( within this groove by fastening devices 17 and 1S, is the shank 19 of the rigid shear blade 12, lhis blade is of novel construction being provided with a longitudinal slot to define spaced members 20 which are connected at their outer ends as shown at 21.

Mounted upon a pivot 22 which extends through the spaced members Q0 is a movable shear blade 13, the latter comprising lnife portion having` a cuttingl edge 23 and a substantially right singularly disposed arm 24. rlhe blade 13 is thus mounted for pivotal movement between the spaced members E20 and relative lateral movement of the blades 12 and 13 is prevented, so that it is impossible to wedge the material being cut between the blades.

The socketed handle member 11 is similar in construction to the handle member 10, in that it is formed of sheet metal and provided one end with a substantially cylindrical portion Q5 and a llattened portion 26 which terminates in spaced ears 27. These ears are provided with apertures which receive the fastening device 1S so as to pivotally secure the member 25 upon the member 1-1. A linlt 28 has one end pivotally secured to the socketed handle member 11 as shown at Q9 and its opposite end pivotally secured to the arm 24 of the blade 1B as indicated at 30.

rlhe invention is susceptible of various manges in its form, proportions and minor details of construction. and the right is herein reserved. to malte such changes as properly fall within the scope of the appended claim.

Having described the invention what is claimed is pruning' device comprising socketed handle members7 a rigid and movable shear blade connected to said members, said members formed ot sheet metal and having' one end bent into sulistantially cylindrical form, a wooden handle inserted thereini, the remaining' handle members flattened and bent longitudinally and spaced apart to provide a longitudinal groove, said rigid blade having its shank secured in said groove, fastening devices adapted to' secure the shank therein and said blade being provided With va longitudinal slot to define spaced members which are connected at their` outer ends, a pivot member extending through said spaced members and said movable bla-de mounted thereon, the latter consisting,` of a knife portion having a cutting` edge and a right angularly disposed arm, one of said handle 10 members being formed of sheet metal and provided at one end With a cylindrical portion and a flattened portion which terminates in spaced ears, said ears having apertures therein to.receive said fastening device, a link having one end pivotally secured to one of the socket handles and its opposite end pivotally secured to one of the right angularly disposed arms of said movable blade.

n testimony whereof I aliX my signature.

MAJOR PHILBRT.
